Core Function

DS200LDCCH1AGA LDCC drive control LAN communication board is core control hardware for GE EX2000 excitation system. It adopts four‑processor collaborative architecture to process drive logic, motor control and I/O signal conversion. It realizes real‑time data interaction between Directo‑Matic 2000 exciter/drive unit and turbine main control system through LAN communication. Non‑volatile flash memory stores drive configuration parameters and application software. It provides local debugging interface and dual reset mechanism, completes excitation drive regulation, signal acquisition and fault diagnosis functions. It is an important control carrier for generator excitation adjustment, ensures stable and reliable operation of excitation drive unit under long‑term industrial working conditions.

Product Details

DS200LDCCH1AGA belongs to LDCC series drive control communication board of GE EX2000 excitation control system.

This multi‑processor integrated board is installed in EX2000 excitation cabinet. Four independent on‑board processors undertake different computing tasks respectively, process customer I/O, drive and motor control functions. LAN control processor realizes real‑time network communication for drive equipment. Non‑volatile PROM keeps configuration data when power off. Hardware and software double reset mode facilitates on‑site fault recovery. LED status lamps help engineers quickly judge board running condition. Conformal coated circuit board improves anti‑vibration, moisture‑proof and anti‑electromagnetic‑interference performance, adapts to harsh working environment of power‑plant excitation cabinet. Widely applied in gas‑steam turbine generator EX2000 excitation system for excitation drive control and data communication processing.

It belongs to critical drive control spare‑part for EX2000 excitation system, widely used in overhaul and renovation projects of power generation units. It is important spare hardware for drive loop debugging and defective DS200LDCCH1AGA board replacement.
